Self-service that takes seconds.
The self-service tablet interface for FEEL EAT’s smart-fridge ecosystem — scan a badge or QR, browse fresh chef-prepared meals, and complete a purchase in workplaces and shared spaces.
A kiosk gets ten seconds of patience.
In a workplace lunch rush, nobody reads instructions. The kiosk had to work for a first-time user holding a sandwich and a phone: scan a badge, see the meals, pay, done — and it had to survive being a public, unattended touchscreen running all day, every day.
We designed for the queue behind the user: badge and QR identification, a menu readable at arm’s length, and checkout measured in seconds — on hardened kiosk-mode tablets that recover from anything without a site visit, wired to the same inventory spine as the fridges.
In production the kiosk disappears into the lunch rush: the median order completes in 42 seconds, uptime holds at 99.7%, and payments clear at 99.4% — on hardened kiosk-mode hardware that gets fixed remotely, not by a site visit.
Public hardware, zero supervision.
A kiosk in a lunch rush gets ten seconds of patience — and there is no one standing next to it to help.
First-time users, every time.
An unattended public touchscreen has to explain itself to a queue.
- No staff to rescue — every moment of confusion is an abandoned purchase.
- Ten-second patience — instructions don’t get read in a lunch rush.
- Public hardware abuse — all-day tapping, spills, network drops and reboots.
- Payment under pressure — a failed charge in front of a queue kills trust instantly.
A flow measured in seconds.
Badge in, meals visible, paid — engineered for the queue behind the user.
- Badge & QR identification — a known, payable user in one scan.
- Menu at arm’s length — readable, tappable, allergens flagged upfront.
- 42-second median order — checkout engineered down to seconds, 99.4% payment success.
- Self-healing kiosk mode — tablets recover from anything without a site visit.
Ten seconds, start to fed.
A public interface engineered for speed, abuse and zero supervision.
Badge & QR identification
Tap a badge or scan a code — identity and payment resolved without an account dance.
Arm’s-length menu
Chef-prepared meals with photos, allergens and prices — readable from the queue.
Seconds-fast checkout
Pick, confirm, charged. The interaction is over before impatience starts.
Kiosk-mode hardening
Locked-down tablets that auto-recover from crashes, reboots and curious fingers.
Shared inventory spine
Live stock from the same platform as the fridges — sold out means actually sold out.
Remote fleet care
Monitoring, content updates and diagnostics pushed remotely — no technician dispatch.
Engineered against the lunch rush.
Four phases, timed with a stopwatch in real queues.
Conceptualisation
Timed real lunch queues — where the seconds go, and where first-time users stall.
Design
An arm’s-length interface: huge targets, minimal text, allergen flags before the tap.
Development
The Android kiosk app on the FeelEat inventory spine, payments built in.
Deployment
Hardened kiosk-mode fleet rollout — 99.7% uptime in production.
What kept us up at night.
The problems that decided whether the product worked at all.
99.7% uptime, unattended
Public tablets crash, lose network and get rebooted by cleaners. Watchdog recovery and kiosk-mode hardening keep the fleet up without site visits.
Payments at queue speed
99.4% payment success under lunch-rush load — retries and fallbacks invisible to the user holding a sandwich.
Inventory in sync with the fridges
The kiosk sells from the same live stock as the fridge doors — one spine, no overselling, no disappointed queue.
Tech stack.
The same spine as the fridges, on a public tablet.
Numbers the owners watch.
The kiosk extended unmanned retail into spaces a fridge alone could not serve.
Fast enough for the lunch-rush queue — the kiosk never becomes the bottleneck.
Hardened tablets that recover from anything — without a site visit.
Checkout that simply works, transaction after transaction.
Keep exploring.
Every project here is live, paid for, and earning revenue for its owners.
